The 240mm/50 Modèle 1902 gun was a heavy naval gun and Coastal defense gun of the French Navy.

The type was used on the Danton-class battleships as secondary battery, mounted in six twin turrets.

The guns were later used as coastal artillery after the ships were broken up, and served during the Second World War, notably in the Battle of Dakar. One open-top twin gun turret is preserved at the battery Castel Gorée, where it has been installed after 1934 to the older coastal defence armoured turret.

Two further examples in single open barbettes are preserved near the Jesus Christ Statue at Vũng Tàu in reasonably good condition. These emplacements were part of a system of coastal fortifications constructed in French Indochina during the early 20th century.
